North Atlantic Ocean, East and West Pacific Ocean along with Arabian Sea and Bay of Bengal are the basins for the formation of cyclones. West Pacific Ocean is the most active cyclone basin in terms of formation of cyclone storms. As per the records, 30% of total global tropical cyclone develops in this area only.
